The Ox-Files: 'Mass cow sacrifices by aliens' sent White House into panic, FBI records reveal

Cows were sacrificed by aliens sending the White House into a panic declassified FBI files have revealed.

It is claimed that more than 8,000 cows were abducted by UFOs before they were mutilated and thrown back down to earth over the southern United States during the 1970s.

The memo is one of thousands of previously unreleased classified files that the bureau has made public in a new online resource called The Vault.Close encounters of a herd kind: Farmers continue to believe their cattle are being targeted by extraterrestrial beings

One investigator's theory was that 'these animals are picked up by aircraft, mutilated elsewhere and returned and dropped from aircraft.

'Identical mutilations have been taking place all over the south west. whoever is responsible is well organised with boundless technology, financing and secrecy.'

When news of the cow abductions reached the White House in 1979, there was fear.

'The materials sent to me indicate one of the strangest phenomenon in my memory,' said the then US Attorney General Griffin Bell in a letter to senator Harrison Schmitt, according to The Sun newspaper.

Mr Schmitt represented New Mexico, where countless incidents were reported at a ranch in Dulce, a small town in the north of the State.

In one case an 11-month old bull was dropped close to someone's house from an aircraft and its sex organs had been removed.

The police report about the incident said: 'The bull sustained visible bruises around the brisket seeming to indicate that a strap was used to life and lower the animal from the aircraft... flesh underneath the hide was pinkish in colour.

'A probably explanation for the pinkish blood is a control type of radiation used to kill the animal... both the liver and the heart were mushy. Both organs had the texture and consistency of peanut butter.'ROSWELL MEMOROSWELL MEMO

FBI agents were dispatched to farms across the country upon reports to probe the abductions.

A report from the farm in Dulce during 1976 said that a suspect aircraft had landed and left three pod marks in a triangular shape.

A further report commissioned in 1979 added: 'The Department of Justice advised that their criminal division has been aware of the phenomenon of animals being mutilated in a manner that would indicate such acts were performed by persons as part of a ritual or ceremony.'

The FBI added that other possible theories for the mutilation of the animals was as a result of biological warfare or 'unidentified objects' were to blame.Fact or fiction: A memo sent regarding the Roswell incident in 1947 said that three 'flying saucers' were found that contained the bodies of alien pilots

The documents about the cows is just one among thousands of files released by the FBI.

Another secret document released as part of the projects detailed how police and army officers witnessed a UFO exploding over Utah in April 1949.

The top secret document reveals how an army guard, a policeman and a highway patrol, who were all miles apart, each saw a UFO, which they said exploded over mountains near Logan, north of Salt Lake City.X-RAY SPECS FOR FBI AGENTS

The FBI investigated whether it could teach its agents to see through walls, one memo details.

In the document, written by agent WA Branigan in July 1957, it says that if extrasensory perception could be mastered then the 'possibilities are endless.'

It continues that the Bureau cannot afford to not investigate further, so later that month they held a secret meeting with William Foos.

Foos claimed he could make the blind see and did a stage show where his blindfolded daughter would read a book.

However an investigation revealed the blindfold contained tiny holes and the demonstrations were concluded as 'merely tricks.'

Another file released involves FBI director J. Edgar Hoover and details of the infamous Roswell incident in 1947.

The memo claims that the air force recovered three 'flying saucers' which contained the bodies of alien pilots.

The aliens were described as being 3ft tall with human like bodies, which were dressed in a fine metallic cloth.

The memos from Hoover are the only evidence that the Roswell incident did in fact take place - and the names of the FBI staff involved have been withheld...
